Dynamic vWLAN Creation and Deletion in Fixed Access Network Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In a Fixed Access Network Sharing environment, Virtual Network Operators (VNOs) face challenges in efficiently creating and deleting Virtual WLANs (vWLANs) in hotspots/hot-zones, leading to resource wastage and limited flexibility, as existing solutions do not allow for dynamic adjustment based on subscriber requirements.
Innovation Solution
A method is introduced that enables dynamic creation and deletion of vWLANs by coordinating between Infrastructure Providers (InPs) and VNOs, involving user equipment, access points, and network controllers to broadcast SSIDs, authenticate requests, and manage vWLAN parameters, allowing for on-demand creation and deletion based on user presence and demand.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If VNOs deploy vWLANs in public hotspots to cover large areas and attract nomadic subscribers, then service coverage and subscriber attraction are improved, but resource waste increases when vWLANs are deployed in areas without subscribers
Solution Approach 1:
The patent implements dynamic creation and deletion of vWLANs based on real-time subscriber detection. When a subscriber enters a hotspot area, the system dynamically creates a vWLAN for that location. When no subscribers are present for a defined period, the vWLAN is automatically deleted. This dynamic adjustment allows the network to adapt to changing subscriber patterns, providing coverage where needed while avoiding resource waste in empty areas.
Solution Approach 2:
The system establishes a feedback mechanism where access points continuously monitor subscriber presence in hotspot areas and report this information to the network controller. Based on this feedback, the controller makes intelligent decisions about vWLAN creation and deletion. The feedback loop ensures that vWLAN deployment is driven by actual subscriber demand rather than static pre-configuration, optimizing both coverage and resource utilization.
2Ease of operation
If VNOs pre-deploy vWLANs in all potential hotspot areas, then service availability is improved, but network complexity and resource consumption increase
Solution Approach 1:
Instead of static pre-deployment, the system uses dynamic vWLAN creation triggered by subscriber presence. The network transitions from a static configuration model to a dynamic one where vWLANs are created on-demand. This reduces the number of active vWLANs at any given time, simplifying network management while maintaining service availability when subscribers are present.
Solution Approach 2:
The system enables self-service operation where the network automatically detects subscriber presence, creates appropriate vWLANs, and manages their lifecycle without manual intervention. The access points and network controller work autonomously to monitor, decide, create, and delete vWLANs based on real-time conditions, reducing operational complexity while ensuring service availability.
3Ease of manufacture
If manual configuration of vWLANs is used in FANS environment, then setup simplicity is maintained, but flexibility and responsiveness to subscriber requirements deteriorate
Solution Approach 1:
The patent implements automated self-service functionality where the network system itself performs the complex tasks of vWLAN configuration, creation, and management. The network controller automatically processes subscriber authentication requests, determines optimal vWLAN creation, configures appropriate parameters, and manages deletion. This eliminates the need for manual configuration while providing high flexibility and responsiveness to subscriber requirements.
Solution Approach 2:
The system dynamically changes network parameters such as vWLAN SSIDs, authentication credentials, and operational status based on real-time subscriber presence and requirements. These parameter changes are automatically adjusted without manual intervention, allowing the network to remain simple to operate while being highly adaptable to changing conditions and subscriber needs.

AI summary
A new interact procedure among a user equipment, an infrastructure provider, a virtual network operator and a corresponding access node and a corresponding access point is provided. Thus, the vWLAN can be created and deleted dynamically for the virtual network operator, such that the vWLAN of the virtual network operator can be utilized efficiently. Thereby, the virtual network operator can deploy its vWLANs in the hotspots dynamically according to the requirement. The flexibility is enhanced, while the requirement for the virtual network operator and actual subscription is met.
